The numerous additions that have been made to our local 

 flora by the Botanical section of the Academy are mainly due to 

 the energy of Mr. Ivan M. Johnston of Upland in thoroughly 

 exploring the San Gabriel Mts. in his neighborhood. All the 

 additions to which no name is attached are his records. Many 

 plants in the list are not infrequent in the San Bernardino Mts., 

 but have not hitherto been accredited to our mountains. 



Senecio triangularis and Arabis platysperma natives of the 

 Sierras are here far out of range. Cneordium dumosum at La- 

 guna has extended its northern limit. Among alien immigrants 

 Paspalnm dilatatum is new to the state, and Euphorbia lathyrus 

 and Bidens frondosa are new to So. California. 



ADDITIONS TO THE LICHEN FLORA OF SOUTHERN 



CALIFORNIA 

 By Ge;orgs L. Moxluy. 



NOT many years ago I collected a few of the more striking 

 Lichens and sent them with some other plants to the 

 U. S. National Museum. I was informed that the Museum 

 had no specialists in the Mosses or Lichens and that my spec- 

 imens had been sent to certain others for determination. The 

 Lichens were sent to Mr. G. K. Merrill, of Rockland, Maine, 

 who, in subsequent correspondence, asked me to continue col- 

 lecting for him, "particularly in such places as are outside the 

 district represented by the Hasse list." 



On Sept. 3rd, 1917, I collected three specimens in Eaton 

 Canyon which, to my surprise, Mr. Merrill said were heretofore 

 unreported from this region. 



"Parmclia dubia (Wulf.) Schaer. The specimens are poor 

 and without fruit, but the determination seems satisfactory. The 

 name does not appear in the Hasse or Herre lists, and perforce 

 the plant is new to California. Hasse may have enumerated it 

 under the name of P. olivetorum, but I have never seen the thing 

 that he called olivetorum. It (meaning my specimen) is 'not P. 

 olivetorum, that is certain." I have quoted from Mr. Merrill's 

 letter thus far. Referring to Dr. Hasse's Lichen Flora of South- 

 ern California I find that his specimen of Parmelia olivetorum 

 (Ach.) Nyl. was determined by Dr. W. Nylander himself. There-
